AC compressors/HACR Fusing


Recommended Posts

One of the items I check is the maximum circuit breaker size for a unit and check to make sure that the proper size breaker is in the panel.

Today I came across a matched set of compressors. The 2 ton unit called for a 40amp HACR and the three ton called for a 15 amp HACR.

This seemed quite odd to me, I usually see larger units with larger breakers.

As I said, they are identical units, except size.
